I would say the kids who need it the most are those who with low income and not top but still decent academic capabilities, who are likely to be accepted by a good state college with full tuition and living aid, yet so often end up not even considering to apply to them due to lack of information, choose a nearby community college, take jobs to support family living, not finish the long physics and math prereq chain to transfer because of lack of time to study, lack of information, difficulty of registering popular courses, and so many other reasons, and ultimately not finishing college.
